How to add VAT to a price
When a price is quoted before VAT, calculate the tax by multiplying the net amount by the VAT percentage. Then add the VAT amount to the net price. The calculator above performs both steps automatically and supports any percentage.
Gross price = Net price × (1 + VAT rate ÷ 100)
Worked examples
At 20% VAT, a net price of 100 has VAT of 20 and a gross price of 120. At 21%, the same net price becomes 121. At 23%, it becomes 123.
Using a custom VAT percentage
You can type any VAT rate into the calculator, including decimal percentages such as 5.5%, 13.5% or 25.5%. Country presets are provided for convenience, but the applicable rate depends on the transaction.
VAT rules can vary by product, service and region. Verify the applicable rate with the relevant tax authority when the calculation is used for tax reporting, invoicing or compliance.
